Int 60/AH=00h

MDEBUG - GET STATUS

AH = 00h
DS:SI -> password or a null byte

Return:
AX = return code
FFFEh password is invalid
FFFDh display mode is invalid
else successful
ES = value of the monitor register SE
DI = value of the monitor register OF
CH = monitor color
CL = interpreter color
BH = monitor start line
BL = interpreter start line
AH = makecode of the hotkey
AL = ASCII code of the hotkey
DL = status of special keys (only SHIFT, ALT, CTRL) for the
hotkey (coded as for the keyboard flag at 0040h:0017h)
DH = basic process number for the communication with drivers
process number for the display driver, DH+1 = process
number for the command driver(s)
DS:SI -> MDEBUG identification table (see #03304)

Program: MDEBUG is a shareware memory-resident debugging tool by Bernd Schemmer, including a memory monitor, an interpreter, and a disassembler

Notes: MDEBUG uses INT 60 by default, but may be directed to any of INT 60 through INT 67; the interrupt handler is preceded by the signature "USERINT" and is not chained. If DS:SI points at a null byte, MDEBUG will prompt for a password if passwords are active; enough stack space must be provided for an INT 10h call (which MDEBUG uses while prompting for the password)
